IMPROVED BED-BOTTOM.

'TO ALL WIIOM IT MAY CONCERN:

Be it known that I, BENJAMIN GRIFFIN, of Lawrence, in the county of Essex, and State of Massachusetts, have invented a new and useful improvement in Bed-Bottoms; and I do herehy declare that the following is a fulland exact description thereof', reference being had to the accompanying drawings and t0 the letters of reference marked thereon.

To enable'others skilled in the art to make and use myinvenftion, Iwill proceed to describe its construction and operation.

Figure 1 represents an upper or top view.

Figure 24 represents a. side piece or rail.

Figure 3 represents head and foot bars.

Figure 4 represents end View and connection ofthe slut to the concaved bar.

Figure 5 represents the sluts with wireihooks in.

Figure 6 represent vfull-size wire hooks.

Figure 7 represents full-size staple.

Letter A represents side piece or rail, or part offrame. D represents the head and foot bars. C represents the slut with the wire hooks connected. D represents the wire that goes across the openings iu said har to hang the slats on. E represents wire hooks, as made in the slat, as shown in iig. F represents mortise in side rail to receive the tenon on the hars which make the frame. G represents tenori onsaid bars'. I'I represents the place to pnt the slat in said bars. I represents the full-size staple. When the slats are hung in the frame' they give an easy vibration to and fro of the shit, and when the pressure is on it shortens them and allows the swinging in a little ofthe wire hooks E, which enables the slat G to spring down and return without making any squeaking noise. I make the slot G two land a half in'chcs wide, nine-sixteenths thick, and bore the holes near the end. I then put in a straight piece of wircand bend it inte hooks, as shown lin'lletter E. I make the hars B ont of two by three stuff, and cut out to receive free play for the slut G. I then take a straight piece of wire, D, bend it down at each end about one inch, and nnike the holes in the har B near euch end, and drive in the wire ends, as shown in fig. 3, and then fasten with wire staples, us secnin iig. 1v. I make the side rail A six feet long, three-fourths to one-sixteenth thick, and mortiscd near each end to receive said hars. When I put the sluts in I run both ends under the cross-wire D; then I hook on one end :it u time, and the slut can be turned over und hooked on one Vside as Well :is the other, in case they should got bent u little by using. In having the slat so thin, and hung in this wayit gives u great elasticity to the slut und makes u. very strong, durable, and-economical und cheap spring-hed bottom.

What I claim as my invention, and desire to secure hy Letters Patent, is-

I claim the cross-wire D, when connected'with the eoncaved har, for the purpose set fortlnund the swinging hooks. when combined with the slat for the purpose specified.
